Differences#
- The boot screen is completely different, with an animated Sega logo coming in from the bottom of the screen and the Master System logo coming in from the right side. Further, both logos are greatly different from the final (the early Master System logo is known to be in at least one game, Safari Hunt, albeit unused):

- The BIOS checks for the strings COPYRIGHTSEGA and COPYRIGHT SEGA at $f7e0 in order to check if a cartridge/card is inserted.
- Due to the different strings checked, only two games can run on this version of the BIOS: Choplifter and the Japanese version of Fantasy Zone.
- No region checking is done on the inserted cartridge/card.
- No sound engine is present.
